摘　　要：文章采用ABAQUS有限元软件建立了5根再生混凝土柱数值模型,进行轴压作用下不同设计变量对再生混凝土柱受力性能的研究。轴压作用下再生混凝土柱的破坏形式与普通混凝土柱类似;随着再生骨料取代率和长细比的提高,柱的轴心受压承载力降低;随着再生骨料取代率的增加,柱的侧向挠度减小。文章建立的ABAQUS有限元模型可以进行类似轴压作用下再生混凝土构件的受力行为模拟。In this paper, ABAQUS finite element software is used to establish five numerical models of recycled concrete columns,and the mechanical properties of recycled concrete columns under axial compression are studied with different design variables. The results show that the failure mode of the recycled concrete columns under axial compression is similar to that of the ordinary concrete columns;With the increase of replacement ratio and slenderness ratio of recycled aggregate, the axial bearing capacity of columns decreases;With the increase of replacement rate of recycled aggregate, the lateral deflection of the column decreases. The ABAQUS finite element model established in this paper can simulate the mechanical behavior of recycled concrete members under similar axial compression.
